Netafim 3/4 Series 80 Control Valve 24VAC 2W Encapsulated Solenoid

Netafim 3/4 Series 80 Control Valve

A mist bench or a drip zone is only as accurate as the valve that opens and closes it. This Netafim valve is the 3/4 inch globe size of its Series 80 nylon line, set up as a standard 2-way, normally closed electric valve. Netafim rates it for flows from 0.01 to 26 GPM, with the low end tested by the Center for Irrigation Technology in Fresno. Operating pressure runs from 7 to 150 psi, with water up to 140 F. It reacts quickly when opening and closing, and a fully supported diaphragm gives a drip-tight seal. That quick, clean shutoff matters on short mist cycles where a few seconds of extra flow changes the result. Friction loss through the body is very low, which lets one valve cover a wide range of zone sizes. A flow control stem on top throttles the valve by hand from fully closed to full capacity. Command water enters through a labyrinth inlet that resists clogging, which suits dirty and reclaimed water. The body, bonnet and diaphragm seat are glass reinforced polyamide. Nuts, bolts and washers are 304 stainless steel, and the spring is 302 stainless. Netafim lists the valve for mildly corrosive and mildly acidic water.

Wiring and Running a 24VAC Solenoid Valve

The solenoid runs on 24VAC with a tolerance of plus or minus 10 percent. Netafim puts inrush current at 0.22 A and holding current at 0.095 A. Those low figures allow long wire runs from the valve back to the controller. Netafim also states the valve works with all major manufacturers' 2-wire control systems. On the 3/4 and 1 inch sizes, Netafim fits an encapsulated solenoid and an improved manual selector. The selector bleeds the valve internally for a manual run without moving the solenoid. The solenoid has no diode, which keeps it stable through voltage swings and less sensitive to dirt. Install the valve downstream of the filter so clean water reaches the diaphragm. Netafim calls the Series 80 optimal for vertical installations. Seal the threaded ends with tape and tighten by hand plus a small turn. Connect the solenoid leads with waterproof wire connectors suited to buried or wet locations. Open the manual selector to flush the line before running the zone from the controller. Then set the flow control stem to trim the zone flow as needed. The valve fits greenhouse and nursery work, master valve duty and remote or automated control.
